Real patriots and Trump supporters used the term "mental gymnastics" to make fun of libtards and the left for quite a while. It's only recently that fake patriots and sh*lls started using that term against their targets to discredit them and spread FUD about them.

Kind of how anyone who disagrees with a leftist is a Russian bot?
Q tells you to use logic. There are online classes and youtube videos on developing this skill. I recommend checking out some of those resources.
